Training for a trek through the Himalaya or an ascent of Mount Kilimanjaro can be tricky when you live at sea level. However, the hypoxic machine at SP Health in London can help prepare your body for the trip by filtering out oxygen in the air, simulating higher altitudes. Even if you dont have a trip planned, you can still reap benefits from this machine. Altitude training can help you increase fitness, improve circulation and lower blood pressure.
